Well, I used Doc's Interstellar mod for the system, since I tried replicating one of the best shots in that movie, this one. I adjusted the exposure of stars and galaxies to what I thought would be good to work with, flipped the perspective horizontally (because from the original perspective, the accretion disk was too bright and the other side was dimmer), and took a screenshot. In Photoshop, I flipped and color corrected it a bit to match the bluer look of the accretion disk in the movie, and then used that as a base to make ton of layers that add bloom/glow and other effects.

Kip Thorne wrote in 'The Science of Interstellar', that Miller's Planet should really be inside the inner radius of the accretion disk. They just wanted so early in the film viewers do not get too overwhelmed. I have a few pictures taken, how that might look.

that Miller's Planet should really be inside the inner radius of the accretion disk.

SpaceEngineer and I discussed this in depth and settled on it being outside for the system addon. The engine has a few bugs when you put it so close, such as glitchy warp effect and strange lighting and that close to the black hole is quite unrealistic for an ocean world.

Not likely, but possible, according to Kip Thorne. The planet must be so close to Gargantua to have a time ratio of one hour to 7 years. That's why he also has the 1.2 kilometers high waves. The planet has the shape of an egg, and rocks back and forth. According to Kip Thorne.

I trust that Kip's calculations for the time dilation, tidal force induced rocking, and waves on that planet are correct, but it does all begin with the assumption that a planet would be in orbit there in the first place, and that's not a reasonable assumption at all.
